At a makeshift shelter in a school in Mekelle, capital of Ethiopia’s Tigray region, Gezae Wolderaphael, an aquiline-featured young sesame farmer, shows what he says are rifle butt and knife wounds on his face and shoulder. The injuries, he says, were inflicted by members of an assortment of forces who surrounded him in the western Tigrayan town of Mai Kadra last November after Abiy Ahmed, Ethiopia’s prime minister, ordered federal troops to take control of the region.
